The range of a lighthouse is the maximum distance at which its light is visible. in the figure, point a is the farthest point from which it is possible to see the light at the top of the lighthouse l. the distance along earth, s, is the range. assuming that the radius of the earth is 4000 miles, find the range of marblehead lighthouse to the nearest tenth of a mile. enter only the number. (hint: notice the right triangle eal with right angle a. find the length el, then subtract the radius of the earth to find the height of the lighthouse.)
